Model 969-9191
The rack adapter shown in Fig. 1 is a 19” modular chassis system based on DIN
41494 part 5 manufactured by “Eurocard”.
Fig. 1 - Rack adapter 3 units
The modular chassis accepts standard 3U control units and provides mechanical
mounting in cases or racks corresponding to the dimensional requirements of 19”
front panels (DIN 41494 part 1).
The basic structure of this modular chassis system provides a further advantage. The
aluminum side panels are connected cross extrusions by four screws to give low-
weight strength and stability. This system reduces mounting times and cuts
mechanical systems down to a minimum.
Low chassis height provides easy mounting on chassis runners.
Telescopic slides may be fixed to standard mounting holes on the side panels.
Assemble the modular chassis as of Fig. 2 with the cross extrusion (3) so far enough
to support the control units to be installed.

where
U (mounting height) is multiple of the height unit 1U = 44.45 mm = 1¾”
HP (mounting width) is a multiple of the horizontal pitch (HP)
maximum of 84 HP
1 HP = 5.08 mm
Total width of the modular chassis = 482.6 mm = 19”.
DISPOSAL
Meaning of the "WEEE" logo found in labels
The following symbol is applied in accordance with the EC WEEE (Waste Electrical and
Electronic Equipment) Directive.
This symbol (valid only in countries of the European Community) indicates that the
product it applies to must NOT be disposed of together with ordinary domestic or industrial
waste but must be sent to a differentiated waste collection system.
The end user is therefore invited to contact the supplier of the device, whether the Parent
Company or a retailer, to initiate the collection and disposal process after checking the
contractual terms and conditions of sale.
